Thread: Really simple first C program

Hi there was hoping someone might be able to help me out. It's very easy my first C assignment however I'm stuck. It's supposed to train a kid how to do their multiplication tables. I can't figure out how to recognise an incorrect answer. This is what I have below but it won't compile as their is one error "identifier user_answer"

[code]
#include <stdio.h>
main()
{
int times_tables, correct_answer,user_answer;
int counter = 1;
int correct_answer_counter = 0;
int incorrect_counter = 0;

printf("Please enter the times tables you wish to be tested on between 1-12\n");
scanf("%d",&times_tables);
printf("You are now going to be tested on your %d times tables\n",times_tables);
correct_answer = times_tables * counter;
for (user_answer=times_tables*counter;counter < 13; counter++)/*This is where our loop begins.*/
{
printf("%d * %d=\n" ,times_tables,counter);
scanf("%d",&user_answer);
if user_answer = times_tables*counter;
printf("This is not the right answer please try again");
incorrect_counter++;

}



}
[code/]

I made a few corrections.

Code:

#include <stdio.h>

int main()
{
int times_tables, correct_answer,user_answer;
int counter;
int correct_answer_counter = 0;
int incorrect_counter = 0;

printf("Please enter the times tables you wish to be tested on between 1-12\n");
scanf("%d", & times_tables);
printf("You are now going to be tested on your %d times tables\n",times_tables);

for (counter=1;counter < 13; counter++)
{
printf("%d * %d=" ,times_tables,counter);
scanf("%d",&user_answer);
correct_answer = times_tables * counter;
if (user_answer != correct_answer)
{
    printf("This is not the right answer please try again\n");
    incorrect_counter++;
    counter--;
}
}

printf("Incorrect Answers: %d", incorrect_counter);
}

Salem,

Sorry about the code tags.

Dr Zoidberg,

Thank you very much. I know it seems very easy to you guys but I was getting a little fustrated that it wasn't working out. Much appreciated.
